pseudocode Environment in Latex

I am trying to write the below algorithm in Latex but failed to get the symbols which are highlighted in red.

• Does latex support this symbol or I am making a mistake in the script?

Example script:

usepackage[ruled,vlined]{algorithm2e}
usepackage{algorithmic}

begin{algorithm}
SetAlgoLined
KwResult{Latex algorithm}
 initialization;
 While{While condition}{
  instructions;
  eIf{condition}{
   instructions1;
   instructions2;
   }{
   instructions3;
  }
 }
